Jeremy 5.0 out of 5 stars I used to think Bose was the best, then I started looking into it. I played the Pink Floyd Dark side of the moon CD on a normal system (2.1) and then on the Bose. I noticed several instruments that were cut out on the Bose system. They were all higher frequency noises. I then played a Five Iron Frenzy CD that uses a lot of trumpets. It was weird, I could've sworn there were trumpets in it. The Bose CD cut them out. I found out later, these tweeters they use for the cubes are cruddy paper speakers. They try to drive them into the mid-range (not good) and I also took apart a Bose subwoofer from this series while repairing it. I found out they were 3 mid-range speakers that are driven into low frequencies. I noticed one of the had blown the paper speaker and the foam from driving them too low. The paper on the satellite looks manilla, and was very fragile. It reminded me of the speakers you get at radio shack. The system sounds decent, but don't expect to hit all the range of sounds. What really made me wake up is my mom's two infinity bookshelf speakers on a harmon kardonn receiver ended up producing a much wider (and fuller) range of sound. It also sounded better.The bose system tries to trick the ears by using the sub plus the high pitches to equalize and cover the mid-range. This ends up cutting audio quality. I will say, the Matrix (virtual surround) is very good on bose.http://airsportstenerife.com/images/bose-lifestyle-12-repair-manual.pdf I would suggest replacing the speakers if you do use it for the surround feature. You will hit a much broader range. Not really worth the money. You can hear the difference. I used to be a bose believer, but trust me, take your favorite CD and play it in their show room, you will be sorely disappointed. It's like a used car salesman making you drive the best car on the lot for a test drive then replacing it with the crappiest when you buy. There is a massive difference in audio quality. I would only get one of these again if it were provided free. Don't think I would buy one though. Not good enough frequency coverage. FYI: I am not an audiophile, I just have sensitive hearing. I also love vinyl, but I am not a hipster, I just grew up with it and the warmth of vinyl is awesome provided the record is still in good condition.At that time there was no equal in the marketplace and there was only a Sony stereo system to copy the. HAHAHA. poor little Sony. Only after many years is that the sound systems to other brands is that they approach the bose I have. Yet behind the model Acustimass 9. Everything is good only on my system it fails to be able to decode Dolby Digital and DTS the sistem. I ended up doing a upgreed system, bought Acustimass 30 that was the last model of that series acustimass. In short. the sound and powerful and now has been great. I advise everyone to bose and I already have a system that makes all the difference in the market as did the first Lifestyle 12 system VideoWave.I would buy this tv from Bose but my parents only costs 6,600 euros. A brand that is dedicated only to do the same columns have to be good and a brand like Sony, LG, Samsung and others can not be because they sound good at all sorts of things from the world of electronica.When I was going to buy my home theater system, I listened to at least another 5 systems of other brands and other configurations When I heard the Bose Lifestyle 12, I was impressed.https://www.avenueroadadvertising.com/wp-content/plugins/formcraft/file-upload/server/content/files/1626c0403f3cf4---canon-h12228-manual.pdf You definetely get what you pay for; go for it and don't waste your time looking at other brands.

Have you checked that you have the correct input device selected.If the unit is moved and comes back on then it will be definitely that. Otherwise it could be some device which is heating up due to failure and shuts down when it gets to much. When it cools down it starts working again.If not, try to see if you can get someone that's great with fixing electronics to repair it or return it to the manufacturer for a replacement.Check it out.First, but not very likely, a poor earth connection on a connector cable.

When I get home I will measure how conductive the goo has become. It is pretty darn dark brown. I guess I should begin to get scared. Thanks for getting me started! Jeff The CD magazine is stuck and making noise. Could you please send me the instruction on how to fix this problem.So, my question is. My AM25PII still be compatible to AV28 console. Any suggestion or help I really appreciate. Sam Use the BoseLInk output to connect it to your sub. All the particulars of set up and control are in the owner's manual for the AV28. Good luck. Mongkol, I have sent the info you need to your email address. Good Luck.BAIGIANGTOANHOC.COM/upload/files/compustar-1wam-s-manual.pdf Rahul, Thank you for taking care of Geoff, you handled that extremely well. I am having a hard time being on here of late as I am in the midst of a big project and all my computer time is being taken up. As soon as I can get this finished I will be back as usual. Thanks for your patience. Mark B. You can go back to achive through july 6, 2008 all the way down you can see the diagram there for 13 PIN. If you have CD5V console you can change C19 for the display. I hope that will help your problem. Sam I am trying to hook up my bose sub am25 to my yamaha reciver and I've been reading some of the past post and and I have the same problem red and white rca's,sub wire and 3.5 mm plug. can I get you to email me a copy of the schematics, the layouts and the the service manual to show me what I need to do and also can I use all the speakers with the system after I rewire it to work on the reciver and what can I use for the ground and and 10 volt power souce to turn on the sub.Here's the problem, i'm sorry if you've answered this previously but i will continue to look through the older posts to see if this was asked before, I've recently moved and now that i'm trying to connect my Bose Lifestyle 5 and I cant get anything from the speakers. Now I've gone through all the pre-checks that I can think of and still nothing. Everything from the media center works because I've checked that with a headphone and I get sound from all the sources but nothing comes through the acoustimass or the speakers connected to it. I don't even get any indication that the acoustimass is powering up because there is no sound when its powered up; there should be a thump at least. Is there a fuse that could have been blown or something of that nature in the acoustimass that I can change or do you suggest that i return it to Bose to have it serviced? I am only a contributor and do what I can to help others. As far as your problem is concerned this first step is to disconnect the cable from the subwoofer and try powering it up by itself. Just plug it in and if the sub is OK it will come on. (thump) If not then you will have to get inside to check things out. Yes there is a fuse that may be open but then there is quite a bit more going on. Check for continuity between the red and black wires going to the transformer. It should check a relatively low impedance. Beyond this check I'll have to wait till you have the prints and service manual. They have been sent to your email address. I opened it up and fixed the fuse. I can see that LED on control pod turns green after switching it on. But there is no sound out of speakers. When I connect headphone to control pod I can hear sound properly. Could you please let me know what can be wrong.I would like to used it for my Pioneer receiver as my subwoofer but I don't have a diagram how to wire it. So please, anybody can send me the diagram how to wire it. Any help I really appreciate it. Sam I have a Lifestyle 28 Series 2 and no longer get any sound from the speakers. I just tried with headphones and all is OK. I opened up the Acoustimass and the only fuse I can see is fine.I could connect cube speakers directly, but i dont know how to connect the bose Acoustimass to the reciever. Any help would be much appreciated.After I re-connected the system, only left and right speaks have sound no. There is no sound from sub woofer and center and rear speakers. Could you please let me know what I should do.I have Lifestyle 25 Series II subwoofer and Bose lifestyle 20 Music center. I would like to upgrade my lifestyle 20 Music center console to AV38 Media Center. My lifestyle 20 Music center still be compatible to AV38 console. If it is possible, What kind of cable do i need.I Have a Bose Lifestyle 28 system and i have no power light on my acoustic mass module and no sound. I have opened it up and tested the fuse and switch. Both Passed. can you please help me someone. Thanks Can this DVD player be replaced with another IDE DVD player? John Are heard humming into my 321 subwoofer but my two speaker are fine it's just the subwoofer it does not produce bass. Any input greatly appreciated. Sam Thanks all for the wealth of valuable information. I have a Bose Lifestyle 5 Music System with the Acoustimass 9 Speaker system. It has the often mentioned problem of the Subwoofer bass channel not powering up. I do get sound from the 5 small satellite speakers, and I do have volume control, although it seems the channels are not amplified. All functions on the Music center unit do work. I do not get the bump indicating the unit is powering up. I have removed the cover from the subwoofer AM9P unit and found the fuse on the upper circuit board to be good. I have also confirmed the circuit board in the sub is getting 115 volts and that the main transformer has continuity through the red and black leads. I have noted previous threads that talk about the specific location of a failed100 ohm resistor (or other resistors) on the circuit board in the sub that will prevent a thyristor or triac from powering up the amplifier(s). However those discussions were specific the AM15 subwoofer module. If so what is the location and value of the resistor that may be in question. Does any one have the schematic diagram and the component layout for the circuits in the AM9P module. If the resistor fix does not apply to the AM9P module, does anyone know of any other commonly found problem that would prevent the base channel from coming on. I apologize if the solution to this has already been posted. I have spent about 3-4 hours researching the archives and have not been able to find information specific the AM9P, so I attempted the post.Is it possible? I cannot work out what the System Control jack will do on the 20? Any help? Is it possible to hook up the five speakers and powered sub to a pioneer reciever. The connector to the head unit is a RJ45 at the sub end and a mini 8 pin din on the other. If someone could help me with the connection information please Thanks Jim It's connected to a Bose inVisible home system that was built into our house. The issue we've been having is that the sound will cut off intermittently - almost as if it gets tired (or hot). Any thoughts on what it might be. In the meantime, its driving me crazy. Cheers - Nate The music center worked fine, except for the display. I appreciate your help, Mark. Perhaps Mark or another expert can help me with yet another minor problem concerning the woofer amp. When I power up the amp, first I get 3 seconds of silence, then 5 seconds of a hissing, slightly crackling sound, then the music comes on and it sounds terrific. After the set has been turned off, I can start it back up within 2 hours without the hissing start up sound returns. I think it has got something to do with the 2 giant 10.000 uF capacitors that may be leaking a bit, but I'm far from sure. Any clue to this problem is very welcome. I take it the first seconds of silence is normal. What exactly does the cable with jack plugs do. I read somewhere that it sends a 12v signal to the amp, but then what. Does it wake up the amp from hibernation. Does the amp hibarnate, or switch off completely. When the cable is unhooked from the woofer after it has started, the woofer continues to work, but when the jack plug is removed from the music center, all music stops. Why? My amateur assessment is that the Acoustimass unit is not getting power as described by others on this forum. Mark (if you are still out there) - I live in nearby Suwanee and would be interested in paying you to repair it.You are great! I've a Boss Lifestyle 20 system. The CD Magazine was stuck and the Display was not working.This system was originaly a LS-12 as I recall and I upgraded it to the 20 when the CD changer was made available and then add the new subwoofer when the unit supported Dolby. I recently purchased a Audio Authority C-1024a to use with the LS-20 and Harmony 880 remote. I've loaded the codes from the Logitech software tool but still can't get the Bose to respond to commands from the Harmony. The C-1024a is acknowledging commands via LED but no LS-20 response. So I have the following questions; 1) Could you forward the display fix? 2) Could you forward the CD fix? 3) Any ideas on the poor remote range? 4) Any ideas on the dropped SPDIF audio? 5) Any ideas on the lack of C-1024a functionallity. Thanks very much in advance I have an old Bose lifestyle 25 system purchased back in 96'. What happens is the speakers make a loud pop and all audio stops. I then unplug and replug and most times it comes back on for a while and some times wont come back on at all. Thank you for your help in advance. The unit is an old 96' lifestyle 25. My problem is the system makes a loud popping noise and cutting out audio. You then have to unplug and replug the power or power cycle the unit to get it to work again.So please hel me. I have a question is possible the Home teathre acces in my country??? I must buy a voltage converter??? and additionaly buy a frecuency converter too ( From 60 Hz, to 50 Hz). Please help me soon. My best regards I have had my Bose LS 12 since 1998 so I am assuming it is a series 1. I tried to use it for the 1st time in several months the other day and I have no sound. I have checked all of my cables and such and all seem fine. I notice when i turn up the volume that there is no volume display. All of the other displays show such as AM-FM and the station, CD track, etc. I tried playing a CD and using the radio and still no sound. I just plugged in headphones and I do have sound through head phones. Could this be as simple as a fuse somewhere. Any ideas or thoughts would be greatly appreciated. PLEASE make it very clear and use step by step directions. I would need repair for dummies type of instructions. If it is a fuse, please tell me where to find it and what kind i would need to get from like a radio shack type of store. I dont think it would be worth to send it out for repair anymore so I would like to try to correct this on my own. Password: Forgot Password.I have the acoustimass 25 (series II) with 13pin cable. I'd like to hook-up directly to my media center PC. I can provide the audio signal to the RCA but not sure how to provide the 12v to trigger the power to turn the powered sub on. Is this usually provided by the 3.5 jack? (I don't have the lifestyle module). I don't have 8pin cable. I would like to hook my MP3 portable player to this sub and I would like to make a wiring jumper so I can hoold up my MP3 player. Can you show me which pin I need to connect my MP3 player to. Thank you, Minh Can I ask you to help in pinout of 9-pin input. Which pins have to be used in this situation. I've also disassembled the bose subwoofer. I removed the plasticback, then I removed the metalbox. Then I found 2 speakers inside and 4-pin jack on the metalbox. It's probably speakers jack. Maybe it is better to send the signal from yamaha receiver straight away to the speakers bypassing the lifestyle KNOWHOW. What do you think about it. Am I wrong? Please help! I have the same problem. Does anyone know of a source for this switch? Thanks I'd like to connect my bose lifestyle 28 III subwoofer to ordinary receiver (yamaha). There 2 speakers inside subwoofer. But this solution seems to be very odd (it's stupid). Maybe there is some other point inside subwoofer there the LFE-signal from receiver could be provided.I am fairly fluent in circuit design, so if you have a schematic of what each of the pins is for, I may be able to figure something out.I have looked everywhere for a service manual and cannot find one.
